To all whom it'imlay concern/.

Be it known that I, RALPH PLUMMER, a citizen of theUnited States, residing at Baraboo, in the county of Sank and State of Wis- 'consin, have invented new and useful Improvements in Speed-Indicators, of which the following is a specification.

The invention relates to improvements in speed-indicators of a class designed toauto- Inatically indicate on a suitable dial the particular machine.

The main object of the invention is the production of speed-indicators of the class described comprehending a single complete structure'designed to be operably connected to the mechanism to be gaged, the construction including a suitable dial and pointer therefor and means operated by movement of a suitable controller to move the pointer in relation to the dial.

The invention in its preferred form will be described in connection with the following specification, reference being had 'to the accompanying drawings, wherein- Figure 1 is a view in elevation of my im proved speed-indicator. Fig. 2 isa similar view with the dial removed. Fig, 3 is a view in side elevationof the same,- the dial-casing and controlling-sleeve being shown in section.

Referring to the drawings, wherein like numerals of reference designate like parts throughout the several views, myimproved speed-indicator comprises a base 1, provided with athreaded opening 2, by which it may be secured to the base of any suitable machine desired to be ga-ged. The base, which is preferably an integral casting, also comprises bearing-arms 3, in which is suitably mounted a transverse shaft 4, carrying at one end a belt-pulley 5 and at the opposite end a beveled gear 6, the latter being preferably mounted intermediate two of the bearing-arms 3. v

The standard 7 is fixed in the upper end of one of the bearing-arms, being provided on its lower end with a loosely-mounted beveled pinion 8, arranged -to mesh with beveled gears 6, the standard rising vertically from the base, as illustrated.

.9 re resents the dial-casing, being a cylindrical )ody formed with diametrically-opposite openings 10 to permit passage therethrough of the standard 7. The upper end. of the standard is threaded to receive a jamnut 11 to support the dial-casing and lockscale which will serve to nut 12 engaging the standard beyond the casing to secure the parts together. I

13 represents .ball-weights connected by arms 14 to a transverse arm 15, revolubly mounted on the standard and connected by a suitable sleeve to the beveled pinion 8 at a vertically-adjustable collar 16, encircling said standard above the arm 15 to permit independent vertical movement of said arm.

If preferred, the collar 16 may be provided with a set screw 'of ordinary construction, whereby the collar may be adjusted lengthwise the standard to accommodate for a desired movement of the transverse arm 15. The weights are also connected by upwardlyextending arms 17 to a transversely-arranged block 18, positioned on the standard immediately contiguous the dial-casing The construction described provides what will be hereinafter termed the controller mechanism and may be varied in its particular details as desired, as the specific construction of such forms no material part of the present invention.

Sleeve 19 is slidably mounted on the standard 7, having a headed end 20 to engage the lower face of the block 18, the sleeve passing through a suitable o ening in said block and projecting integral y of the dial casing through the lower standard-opening 10 thereof. At the up er end the sleeve is provided with a forward y-projecting arm 21, fr'omthe forward -end of which rises a rack 22, as clearly shown in Fig. 3. A spring 23 is coiled about the standard 7, being terminally connected to the upper end of a sleeve 19 atjone end and at theopposite end secured between block-nuts 24, through the use of which latter the upper terminal of the spring may be adjusted longitudinally of the standard to vary the tension of the spring in an obvious manner. A cross-bar 25 is arranged transversely of the dial-casing. The bearing-strip 26 is secured centrally of the cross-bar '25, being centrally spaced therefrom and terminally bent toward and secured to said bar, as clearly illustrated in Fig. 2. 27 represents the, dial, secured to the forward edge of the casing in any appropriate manner and bearing on its face any desired indicate the speed of any particular mechanism.

28 represents the pointer. movably supported centrally of the dial. being secured on the outer end of a transverse shaft 29, bearios ing in the-dial and in the supporting-strip-26 and cross-bar Aipinion is fixed upon the shaft 29 between the cross-bar and'thexby any suitable belt is communicated to ,the

beveled gear 8., and thereby to the controller described. Centrifugal operation of the con- 'troller spreads the weight 13, vertically decreasing the distance between the transverse arm 15 and the block-18, and as the frame is fixed. against independent vertical movement the latter will move downwardly, drawing" with it sleeve 1-9 and therack 22, operating against the tension ofa'spring' 23'. r The 'de'-' :Scribed movement of the rack rotates the pointer-shaft 29 through operation of the pinion30, thereby-moving thepointer to the proper scale-mark onthe dial, thereby .accu

rately gaging and indicating the speed of'the" initial mechanism. Asitjhe cont'rollerre't'urns to normal position the-spring 23 operates to move the parts'totheir original sitrration 'lhestructure described is simple and read ily adapted for connection with any desired machine. A I

Having'now described my'inven-tion, what 1 claim as new, and desire to secure by .Let-

ters Patent, is I 1.. A speed-indicator comprising abase, a

standard 'risin from the base, a controller" supported on t estandard ,-meanscarried by 'the base for operating the controller, a dial carrying a pointer and supported on the standard; a sleeve slidably mounted on'the standard andconnected with the controller,

and -means intermediate'the sleeve and pointer to operate theylatte'r in the movement e'f the controller. i A, 1 2. A speed-indicator comprising'a base, a

- shaft revplubly mounted in the base, a stand-' ard rising from the base, a controller sup- Dorted on the sta'ndard,means intermediate the shaft and controller for-operating the lat ter in the revolution of the shaft, a dial-casing including the dial and pointer supported v on thequpper' end of the standard, a sleeve movably connected to the controller and slidably engaging the standard, a spring adapted to normally maintain'thesleeve at its up-- 'wardlimit of movement, a rack connected with :the sleeve-and ear meshing with said rack and connected with the pointer.

- 23. A speedeindicator comprising a'base, a

shaft revolubly mounted inthe base, a stand ard rising from the base, a controller supported 'on the standard, means intermediate the shaft and controller for opera-ting the latter inthe revolution of the shaft,- a dial-casing'including the dial and pointer supported on the upper-endof the standard, asleeve movably connected to the controller and slidably engaging'the' standard, a rack connected [with the: sleeve, and gear meshing with said, rack, and connected with the pointer, and a .spring terminally connected to said sleeve and to the standard. I 1 r 4. A speed-indicator comprising a base, a shaft revolubly mounted in the base, a standard rising from the base, a controller sup- :ported on the standard, means intermediate the shaft and controller for o erat'ing the latter in-therevolution of theis aft, a dial-casing including'the' dial-and pointer supported on the upper endof the standard, a sleeve movablyconnected to the controller and slidably engaging the'standard,a-rack connected with thesleeve, and gear meshing with said rack, and connectedwith the pointer, and a spring connected at one end to the sleeve-and adjustably connectedat the opposite end of. the standard;
